PAPER-SHEET-FEEDING MACHINE.

Specification of Letters Patent.

Application filed May 22, 1912. Serial No. 698,999.

' employed whereby the sheets are automatically fed to the machine. Inthe event of an interruption or disturbance occurring in such machines1n order to prevent the sheets from accumulating and causingobstructions,

' the sheet feeding mechanism has to be ing thrown out of action wherebyrapidly rotating and relatively heavy parts such as the combing rollsare ultimately brought to a complete standstill. Inre-starting the sheetfeeding mechanism such heavy parts have obviously to be brought again totheir required rotary speed and this cannot be effect ed withoutdetriment to the working of the machine.

Now according to the present invention the above draw-backs are obviatedby the provision of a device controlled by the at tendantand adapted toso cooperate with the lever operating the combing roll that by theactuation of the device the combing roll is tripped to and held in itshighest position while the remaining parts of the sheet feedmechanismandalso the combing roll continue to operate at their normal speed and thusare always held in readiness for the working.

A constructional form of a device according to the present invention isshown by way of example in the accompanying drawing which shows thelateral elevation of a sheet feeding mechanism provided-with the newcontrolling device.

The sheet feeding mechanism is substantially of the construction shownin my prior Us S. Patent 967077 and consists of a vertically movableslider B which is under the action of a spring C and in opposition tothis spring is held in its lowest position by a lug 9 arranged on arocker E. On the axis F of this rocker is mounted an arm G pivoted towhich is the usual trip lever H.

r011 A it lifts the trip lever H which thereby causes an arm I to bebrought into engages ment with a friction disk K secured to and; 1,driven by the constantly rotating shaft'hii 3 By this engagement the armL an with it. the arm G as well as the arm Eiare forced? back so as tofree the sliderB which is then ing combing roll A to be raised out ofengagement, w; h the sheet into the position indicated in dotted lines.

My new device consists of a double armed,

drawn up by its spring C thereby so aetuatr a lever mechanism M N as tocause the lever 1 which is used to act on the shank N of the lever M andto force the arm N into the dotted line position shown in which thecombing roll is raised out of action. To this end the end of the leverarm N is provided with notches 0 adapted to coiiperate with the rollerarranged on the respective end of the lever T.

Inasmuch as it is' often desirable to adjust a series of sheet-feedingdevices simultaneously the levers T can be connected by a cdmmon rod Pattached to which is a handle U. By rocking the whole of the levers T 80 combing rolls of all' sheet feeding mocha into the dotted linesposition shown the nisms are thrown out of action without affooting thecontinued working of the individual sheet feeding devices.

What- I claim and desire to secure by Letters Patent is In the hereindescribed sheet feeding mechanism. the combination with the combmg rolland the rocking carrierfor said combing roll, a

carrier thereof, of a notched manually operated double armed lever, one

arm of whichcarries a roll freely, resting in the notch of said carrierand which arm is adapted on its manipulation to swing the said carrier50 as to release the combing roll without affecting the continuousoperaarts of the mechanism. In testimony w ereof I have aflixed mysignature in presence of two witnesses.
